Clean Master is an application for cleaning the RAM of smartphone and clear the junk and viruses of the phone. I use this application for last two years but I think it is a virus my smartphone become slow after installing this application.
Layout and design is very good of this app so people install this app but perform is very bad.
It has many features such as clean junk virus and turbo bust.
It is not a useful app to install this app is totaly wastage of time and RAM.
